Wes McKinney commented on ARROW-1389:
-------------------------------------
[~pcmoritz] this can be implemented using ExtensionType / ExtensionArray now
without modifying the Arrow IPC metadata
> [Python] Support arbitrary precision integers
> ---------------------------------------------
>
> Key: ARROW-1389
> URL: https://issues.apache.org/jira/browse/ARROW-1389
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Philipp Moritz
> Priority: Minor
>
> For Python serialization it would be great if we had Arrow support for
> arbitrary precision integers, see the comment in
> https://github.com/apache/arrow/blob/de7c6715ba244e119913bfa31b8de46dbbd450bf/python/pyarrow/tests/test_serialization.py#L183
> Long integers are for example used in the uuid python module and having this
> would increase serialization performance for uuids and also make the code
> cleaner.
> I wonder if this is more generally useful too, any thoughts?
